And all practitioners need to master a flame, and its requirements for flame and fire control techniques are second only to those of the practitioners, and the most common flame in the cultivation realm is the 'Three Flavors True Fire', which is also the only one that Yin Lei can master at present. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

When Yin Lei was trying to practice the sword for himself, he got the weapon technique, which was really a gift in the snow.

Now what Yin Lei is looking at is not but not the 'Gathering and Dispersing Impermanence Formula', but the two chapters that Xie Wusheng made up for him later, perhaps Xie Wusheng was afraid that this 'Gathering and Dispersing Impermanence Formula' would fall into the hands of the enemy after his death, so he erased the two most important chapters.

Now what Yin Lei is holding in his hand is the first chapter of the knowledge of things and the last chapter of the sacrifice chapter, if these two chapters are missing, the 'Gathering and Dispersing Impermanence' will become an ornament.

The mysterious metal that Yin Lei got still doesn't know what it is, originally Yin Lei just wanted to find out what this mysterious metal was from the Knowing Things, but when he saw the Knowledge, he didn't know how to get lost in the strange various items.

After reading in his spare time for these two days, Yin Lei's horizons increased greatly, and among the tens of thousands of metals, Yin Lei found that the raw material 'Jin Jing' that he had obtained to refine Ruyi was only one of the eighteen second-class materials.

This result made Yin Lei very disappointed, and at the same time, Yin Lei's heart became hot again, if he could use better materials to refine Ruyi, would Ruyi's grade be improved? With Ruyi's current function of defying the sky, if he can improve it as a whole, I am afraid that there is nothing to be done about the flying sword used by the Qi practitioner in the Jindan period.

But when Yin Lei saw the nine first-order materials, he immediately dispelled this idea completely, he had never heard of any of these nine first-order materials, what bone silver, fine crystals, slippery weaving, etc., they were all legendary things.

And Yin Lei then also understood that what is needed to practice Ruyi is balance, if one of the materials is improved, the other five materials must also be improved accordingly, if the six materials can be improved, Ruyi doesn't know how far it will go.

But to Yin Lei's surprise, the mysterious metal he got was not any of the nine first-class materials, could it be that he inadvertently obtained one of the three top-level materials?

So Yin Lei once again took out the knowledge chapter with a fiery mood and looked at it carefully.

Yin Lei had never heard of these three top-level materials, so it was difficult for him to judge, but fortunately, there was a detailed introduction to these three materials in the previous chapter.

The first is the flow of magma produced in the depths of the earth for hundreds of millions of years, which is a product of nature, which is the crystallization of countless kinds of metals contained in the rocks of the earth, which is also an alloy.

According to the Records of Knowledge, there are occasional people who get this thing but cannot smelt it, and this thing will not melt even if it is soaked in lava, and it can only be slowly melted when it is sent to the depths of the earth under high pressure and extreme temperature.

Of course, high-level Qi Cultivators and Cultivators in the Tribulation Period can also use the Natal Divine Fire to cultivate them, or those who have a special flame can also cultivate them.

This kind of metal impermanence, it is said that the flow of the two times is not exactly the same, which is also the reason why Yin Lei can't judge whether his mysterious metal is this thing.

The second is immersion gold, which is a special metal produced in the extreme abyss.

When Yin Lei got the 'Fire Pill Secret Technique', he asked the old man of Changchun, since there is a 'Fire Pill Secret Technique', is there also a Water Pill?

The answer is, of course, yes, Shui Dan is a special kind of Dan practice, there are a very few materials that are afraid of high temperatures, and the efficacy of high temperature is completely lost (such as the current artemisinin), then it is necessary to use Shui Dan, but the old man of Changchun also admitted that he has not been exposed to Shui Dan.

This kind of immersion gold is the natural gold formed by the perennial impact and precipitation of the water flow under the high pressure of the extreme abyss, and the immersion gold is rarer than the flowing gold.

However, compared to the third type of metal, there are many more streams, and it is recorded that the third material has only appeared once in the monastic world.

It was a pure, transparent unidentified object, so cold that any liquid that came into contact with it would freeze instantly, and some people said it was not metal at all, but ice for billions of years.

But throwing it into the lava also froze and nothing could damage it, and what it was is still unknown.

In addition to these three top materials, there is also a special material, meteorite.

The metals in meteorites come from outside the sky, which has great uncertainty, most of the metals in meteorites are extremely common, but there are also special metals that do not exist in this world, many of these metals have no use, some are extremely soft, some are extremely hard, some are extremely soft, but there are always some special existences.

The metal in Yin Lei's hand was harder than the 'Golden Essence', but he couldn't be sure whether this mysterious metal was meteoric iron or immersion gold, or something that was not recorded in the 'Gathering and Dispersing Impermanence'.

But no matter what Yin Lei had in his hands, the purification technique and refining technique in this 'Gathering and Dispersing Impermanence Technique' could always be used.

After studying it carefully for a while, he still couldn't tell what was in his hand, Yin Lei put away the 'Gathering and Dispersing Impermanence Technique' with some disappointment, and then he flipped his hand, and a flawless jade bead appeared in his hand.

This is the treasure that Yin Lei just got, the 'Spirit Orb', looking at the 'Spirit Orb' in his hand, Yin Lei couldn't help but think of the 'Spirit Ring' in Dou'er's hand, wouldn't this also be a treasure that could hold the soul? If it's really good, Wan'er has a place to stay.

It's a pity that this orb can be put in a storage bag, and it is not a space magic weapon at all.

Thinking of this, Yin Lei relied on his courage to use his divine sense to go around, the last time the 'Yunling Ring' made him suffer enough, Yin Lei is memory is especially fresh.

As a result, Yin Lei couldn't figure out the role of this jewel with great effort, which couldn't help but make Yin Lei depressed, and he forgot to ask Xie Wusheng about the purpose of this jewel.

Sighing, Yin Lei put the 'Spirit Orb' into his arms, but just when his hand just touched his left sleeve, his body suddenly trembled and stopped, and the next moment Yin Lei's face suddenly turned pale.

Just now, a feeling of extreme fear came from the darkness, Yin Lei had this feeling, the last time Pian Pian was caught and almost killed in eight acres of land, Yin Lei felt this kind of fear at that time.

Then there was a hint of panic in his eyes, and after a few breaths, Yin Lei suddenly stood up violently and said in a trembling voice: "Brother Lin, something happened at home, let's go back quickly." ”

Lin Guodong, who was meditating and pranayama next to him, was shocked when he heard this: "Is something happened to the two Meng seniors?" ”

Yin Lei shook his head solemnly, and Lin Guodong said, "You also used the 'soul training technique' on other people?" ”

"No, something happened to Pian, I have a telepathy with her, let's go back soon."

Lin Guodong has also lived in the territory of the fox clan for half a year, of course he knows the relationship between Yin Lei and Pianpian, and he couldn't help but be shocked when he heard that something happened to Pianpian, he immediately released the flying magic weapon without saying a word, and the two of them jumped on the magic weapon and flew towards the northeast quickly, this time their speed was more than three layers faster than when they came.

……

In the early morning of the next day, before dawn, a group of several young men and women quietly came to the cave where Yin Lei and they had rested.

"Senior Sister Qingyu, are they here?"

A yellow-clothed second year asked softly, after two days of sleepless chasing, they were all a little tired.

"You can't be wrong, baby never missed."

A hint of murder flashed in the eyes of the man who spoke, and he said coldly: "Senior sister doesn't need to make a move, you just stay outside and be careful not to let them run away, and leave this matter to a few of us." ”

"Senior brother, be careful not to give them a chance to perform."

"Senior sister, just rest assured, the five of us will work together to strike a blow, unless he is a god infancy master, it is impossible to live."

After two days of tracking, according to Yin Lei's flight speed and flight altitude, they were confident that the person they were chasing was not a god infancy master.

"Senior brother, don't be careless, I know that senior brother has two intermediate talismans, if you fight head-to-head with the intermediate talismans, you may not be able to kill them with one hit, but there are many chances of sneak attack and plot."

The young man in yellow hesitated slightly when he heard this, and immediately said, "Okay, for the sake of safety, I'll give them a good time." ”

After a while, the five teenagers came to the entrance of the cave more than ten zhang away, in order not to alarm the people inside, and they were afraid that the other party would arrange a warning formation nearby, and the few people would not move forward.

After preparing for a while, the yellow-clothed young man carefully took out a metallic talisman from his arms, glanced at the young man with some reluctance, gritted his teeth and whispered: "I'll urge the talisman first, and then everyone will concentrate on one blow, be sure to kill with one blow, and don't give them a chance to fight back." ”

The other four all nodded, and their eyes fell on the intermediate talisman.

Then the young man in yellow silently operated his spiritual power with a talisman in his hand, and then he waved his hand forward, only to see a huge fire cloud appear in the air, and then the fire cloud gathered in the middle, and a fire snake nearly ten zhang long appeared.

The young man in yellow didn't dare to delay, and as soon as he urged the spirit trick in his hand, the fire snake circled slightly and suddenly plunged towards the cave.

Just as the head of the fire snake was about to enter the cave, the young man in yellow roared in a low voice, "Do it......." ”

Then five magic weapons with different lights also flew towards the cave with a whistling sound, when these five magic weapons flew to the entrance of the cave, the fire snake had already drilled into it, and then there was a loud bang, and the cave spit out flames seven or eight feet away like a volcanic eruption.

At this time, if someone is inside, the ninth layer and nine will die, even if they are lucky enough to escape the catastrophe, don't think about it under the blow of the five magic weapons outside, even if the Divine Infant Monk is attacked like this, the eighth layer will be damaged.
